Guardiola – who takes his side to Sunderland on New Year’s Day – held several talks with his squad during the Club World Cup in America in the summer and believes the breakthrough came there.
He said: “When we went out to Al Hilal, it wasn’t the fact we didn’t win but that we were so good there. It was then holidays so I said: “OK, go on holidays” but I was annoyed because we were good there, good with the guys training, good with the competition.
“The place we were in, Boca Raton in front of the beach, everyone was happy. We made a lot of dinners, a lot of talks, [about] what we have to do next season. What we have to do. We wanted to extend it, just to live that.
“After talking with Pep [Lijnders] and James [French], Manel [Estiarte], Hugo [Viana], Txiki [Begiristain], we turned around and said something changed. Something [you can feel].
“Energy, energy, energy. We lost it last season. We started to train better, compete better.
“It doesn’t mean you are going to win but that you are able to recognise the team. Now it is eight victories in a row. It is not easy but compete in a way we do. We have to improve, absolutely, but this mindset is better.”
